Introduction
This is a manual for the “NAVIGO” electric power unit for wheelchairs. Before you read this manual, check
which product you are using.
This product consists of the left and right drive units, the joystick-equipped controller, the battery, optional
battery bag, the battery charger, and the optional assistant controller. These components, except for the
battery and charger, are already installed to the wheelchair frame. For the initial use, the customer does

these components are installed to the wheelchair that you purchased and that the battery and charger
are included. If you visually notice that any of these components are not installed, are not included, or are
damaged before using the wheelchair, immediately contact the dealer without using the wheelchair.

1. Please Read Before Use
1.1. Foreword
Thank you for purchasing the NAVIGO.
Indication for use: The device NAVIGO is a Powered Wheelchair Conversion Kit and suitable for a dis-
abled person who cannot walk or has restrictions on walking. It is intended for medical purposes to pro-
vide a means for a disabled person to take over the propulsion of the wheelchair and increase mobility
and exibility. Generally speaking, riding in a wheelchair incurs the possible risk of personal injury or dam-
age to the wheelchair from improper use. Depending on the type or extent of the disabilities of the user, it
might be dangerous to travel unaccompanied.
Before using the wheelchair, be sure that not only the user, but also the assistant and controller, has read
this manual to assure full understanding.
(1) The wheelchairs on which the NAVIGO has been installed are wheelchairs for physically handi-
capped people, and legal status of someone in a wheelchair is that of a pedestrian. Make sure to ad-
here to the tra󰀩c rules and manners of a pedestrian.
(2) The NAVIGO 24″ withstands a load of 275 lb (125 kg). Use with a total maximum load including the
chair frame weight of 275 lb (125 kg). NAVIGO 16″ withstands a load of 220 lb (100 kg). Use with a
maximum load included the chair frame weight of 220 lb (100 kg). If the frame on which the NAVIGO
is installed has an even lighter load capacity, ensure that you do not exceed that value.
(3) To help ensure safe use, warning labels are a󰀩xed to this product. Make sure to adhere to the warn-
ing labels. Refer to “1.6. Warning Label Location Diagram” for the locations of the warning labels.
(4) Do not use this product for any purpose other than as an electric wheelchair.
